Shri Kulkarni,Dale A. Frail,Mark H. Wieringa,Ron Ekers,Elaine M. Sadler,R. M. Wark,James L. Higdon,E. S. Phinney,Joshua S. Bloom +8 more
TL;DR: In this paper, radio observations of the supernova SN1998bw, which exploded at about the same time and in the same direction as the γ-ray burst GRB980425, were reported.
Journal ArticleDOI
An Optical and H I Study of NGC 5850: Victim of a High-Speed Encounter?
TL;DR: In this article, the authors presented optical CCD surface photometry and VLA H I observations of NGC 5850, one of the largest and brightest barred spirals of the inner ring variety in the sky.
Journal ArticleDOI
First Detection of PAHs and Warm Molecular Hydrogen in Tidal Dwarf Galaxies
TL;DR: In this article, the Infrared Spectrograph on the Spitzer Space Telescope was used to detect strong polycyclic aromatic hydrocarbon (PAH) emission at 6.2, 7.7, 8.6, 11.3, 12.6 and 16.5 μm, which match models of groups of ~100 carbon atoms with an equal mixture of neutral and ionized PAHs.
Journal ArticleDOI
Radio Observations of the Hubble Deep Field-South Region. I. Survey Description and Initial Results
Ray P. Norris,Minh Huynh,Carole Jackson,B. J. Boyle,Ronald D. Ekers,Daniel A. Mitchell,Robert J. Sault,Mark H. Wieringa,Robert Williams,Andrew M. Hopkins,James L. Higdon +10 more
TL;DR: In this article, the authors describe the results of the Australia Telescope Hubble Deep Field-South radio survey and discuss the properties of a subset of these sources, including starburst galaxies and galaxies powered by an active galactic nucleus.
Journal ArticleDOI
VLT Observations of NGC 1097's "dog-leg" tidal stream
TL;DR: In this paper, the structure and stellar population of two large stellar condensations along one of the faint optical "jet-like" tidal streams associated with the spiral NGC 1097, with the goal of establishing their physical association with the galaxy and their origin.
